Fully Charged: The smart cup that knows what you drink, a massive £1 million TV, and Tesla Motors gifts its electric tech to the world

Vessyl is a smart cup that can ID (and track) your beverages

Tracking food and drinks is an extremely helpful way to manage your daily caloric intake and try to get fit, but having to manually enter everything tends to derail even the best of intentions for busy, tech-savvy folks. But Vessyl, easily the most intelligent cup we’ve ever seen, wants to make things quite a bit easier by automating part of the process.

This smart cup uses a built-in sensor to determine the composition of anything poured into it within about 10 seconds, and will display the results—and then send the data via Bluetooth to the iOS and Android app, allowing you to keep track of all of those empty calories you’re soaking in throughout the day. The Verge reports that it tried out a bevy of beverages and its accuracy impressed, even telling different flavors of sport drinks apart.

Even better, the Pryme feature uses your body metrics and other data to keep tabs on your hydration throughout the day, ever slightly nudging you to take in more of the clear, zero-calorie stuff as needed. It’s available for pre-order today for US$99 with a delivery target of early next year—but if you wait, it’ll go for the standard price of US$199.

Titan makes world’s largest domestic TV at 370in—and £1 million

Looking to upgrade your flat screen? Got a cool million laying around, not to mention an utter wealth of available free space? Consider dropping Titan Screens a line, as they’ve got a new set they’re declaring the world’s largest TV screen for domestic use.

Coming in at a mind-boggling 370in—that’s 8m x 5m—the 4K-compatible Zeus set is reportedly four times larger than the previous top option. Naturally, such extravagant tech comes at a price, and in this case, it’s a cool £1 million. That includes installation and delivery via a custom-built Hummer (well, it better).

According to Titan, half of their sets have already been claimed, leaving just two available. “Having already pre-sold two of our £1m screens—one of which is likely to be installed at the bottom of a very large indoor swimming pool—we are open to serious enquiries in relation to the other two in the range.”

In the mood to make that serious enquiry? You can get in touch via Titan’s website, though it’s unclear if you’ll be able to get the Zeus in time to see the last bits of the World Cup on the football goal-sized screen.

Tesla Motors opens up its electric car patents to all

Few tech CEOs exude cool quite like billionaire Elon Musk, who heads up both SpaceX and Tesla Motors, and he proved it again yesterday by penning a post entitled, “All Our Patent Are Belong to You”—in which he declared Tesla’s electric car patents to be effectively open source.

“Tesla Motors was created to accelerate the advent of sustainable transport,” reads the post. “If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.”

Considering Tesla’s edge in the admittedly very small electric car segment, it’s a surprising move—but Musk says it’s one borne out of frustration that competitors aren’t doing enough to help further the electric car movement. He hopes this move will encourage healthy competition to move the entire industry forward and break away from gas-consuming cars.
